QUESTIONS AND CORRECT DETAILED
ANSWERS | NEWEST 2025
Uncompensated - ANSWER pH and one other value is abnormal
Partial compensation - ANSWER pH, CO2, and HCO3 are all off
Full compensation - ANSWER pH is normal
Acidosis - ANSWER reduces the excitability of cardiovascular muscle, neurons,
skeletal muscle, and smooth muscle.
Alkalosis - ANSWER increases the sensitivity of excitable tissues allowing them
to OVERRESPOND without stimulation
ABG considerations - ANSWER - Assess cardiovascular w/ acidosis (cardiac
arrest from hyperkalemia)
- Assess neuro status
- Fall precautions
Bicarb HC03 - ANSWER kidney compensation (slow and powerful)
Respiratory PaC02 - ANSWER Respiratory compensation (fast but limited)
, Metabolic acidosis causes - ANSWER DKA, Starvation, diarrhea, kidney failure,
dehydration, liver failure, pancreatitis, heavy exercise, seizure activity, fever,
hypoxia, ischemia, ethanol/methanol intoxication
Metabolic acidosis signs and symptoms - ANSWER bradycardia, hypotension,
thready pulse, CNS depression, hyporeflexia, kussmal resp (with resp
compensation), warm, flushed, dry skin.
Metabolic acidosis treatment - ANSWER hydration and medication to treat
underlying problems (DKA - give insulin).
Metabolic alkalosis causes - ANSWER antacids, blood transfusion, sodium
bicarbonate, total parenteral nutrition (TPN), prolonged vomiting, nasogastric
suctioning, hypercortisolism, hyperaldosteronism, Loop/Thiazide diuretics.
